Final answer:
The product of 10*(-6-9i) is -60 - 90i, which is the standard form for complex numbers a + bi, where a and b are real numbers.
Step-by-step explanation:
The question of a complex multiplication problem, which is to calculate 10*(-6-9i).
To solve this, we apply distribution of the real number over the complex number.
Multiplying the real part and the imaginary part separately with 10 gives:
- 10 * (-6) = -60
- 10 * (-9i) = -90i
Therefore, the product is -60 - 90i, which is already in the standard form a + bi for complex numbers where a is the real part and b is the coefficient of the imaginary part i.
